Matthew Green is a UK-based sleep expert with a sharp eye for technology and a growing reputation for demystifying the science of rest. Formerly a tech journalist, Matthew’s journey into the world of sleep began with a simple curiosity: could data and smart devices genuinely improve how we sleep—and by extension, how we live?

What started as a personal experiment with wearables and sleep apps quickly evolved into a deeper fascination with the mechanics of recovery, circadian rhythms, and behavioural change. As someone who once chronicled the rise of consumer tech, Matthew now finds himself at the crossroads of human biology and digital innovation, exploring how the right tools—and the right habits—can unlock better rest.

Today, Matthew translates complex sleep science into practical, tech-savvy guidance for anyone looking to optimise performance, focus, and wellbeing. Through writing, consulting, and speaking, his mission is simple: take sleep seriously—because no upgrade beats a well-rested mind.
